To (all whom it wea concern.-

Be it known that I, JOHN M. 'Goonwm, a

citizen of the United-States, and-a resident of the city ofMountVernoI-i, in the county of' West'chester and State of New York, have invented certain new and useful Improvements Gravity-(lhutes, of which the following is a full, clear, and concise specification.

My invention relates to the construction and support of gravity discharging-chutes of dumping vehiclesg and it consists in certain relative" arrangements, combinations, and

'subcombihations of the several parts, which- Will be hereinafter described, whereby said chutes may be I economically manufactured with great supportin stren th and shock-resisting powers, toget ier. wit i.the least possihis weight and complication, thereby adapting the same to be used upon railway-cars or marine vessels of large carrying capacity.

Referring to the accompanying drawings,

fprniingpart of this application, and in whichlike reference characters designate similar parts, Figure 1 is a cross'sectional elevation of a dumping-car, suchas isnow generally known as the Goodwin dumping-car, provided. with d scharging-chutes constructed according to the present invention. Fig. 2 1s a similar view in detail, showing one chute enlarged. Fig. 3 is a sectional view of Fig. 2 onlhe line 3 3 looking in the direction of the arrows. ig'. 4 is a sectional view of Fig. 2 line at it looking in the direction of the arrows. Figl 5is a similar sectional view of Fig. '2 on line 5 5 thereoflooking in the directionofpthe arrows. Fig. 6 is a similar sectional view online 6 6 of Fig. 2 looking in the direction of thearrows. Fig. 7 is an enlarged 1 "detail view of the blank from which the ten sion or connecting member 1 is formed, and Fig. 8 is an end view of thesame blank after the same has been folded. A The vehicle shown herein comprises the usual receptacle portion with hinged bottom valves G G, which have their inboard ends supported by the two cente valves A,.and the latterware pivoted. on t e longitudinal shaft J so that they may swing downwardly to release the bottom valves and allow the contents of the receptacle to escape. The

center valves, which thus act as detents to thebottonrvalves, are supported n their elevated or closed position-the position shown in Fig. l-by means of two rotary detents C C, respectively carried on rock-shaftsl, coniroiledi'rom the ends "of the vehicle. When either of said shafts is rocked outwardlyso l I to remove the detentC from under the valve" -A, the latter falls. to the position .shown in Fi 2, wherein its upper surface, substantialy coincides withthefplane of the dischargingchute E Fandcooperates with the Specification a Letters Pate t. rant d i l-area 13,1906.

latter to provide a practically continuous surface for the contents of the vehicle to slide upon. The discharging-chute E F isadapted to conduct the said contents to one side of the vehicle, but may be. manipulated to" dump the sanie'directlybeneath the vehicle.

The weight of the vehicle is carried: upon or by two or more I be-ams, which form the longitudinal center sill S and extend, as shown, the length of the car, being" supported at their ends upon bolsters and trucks, (not shown,) and the discharge-chute E F, which is the subject of this invention, is mounted on supporting-frames also carried by the said center sill.

The reference character F designates that. portion of the discharge-chute'which is fixed, and E represents the movable section, which is pivoted on the pins E so as to be capableof adjr tmsait into the position shown in dot.

ted lines to change the direction of discharge justreferred to, Eachframe upon or which. both of these sections are carried is built up and supported as follows: Saddlepieces P are mounted at intervals along the Lbeams. of the center sill S and are preferably securely fastened to them, these saddlepieces being formed as castings or forgings andfbeing the parts which provide the jourrial-seats for the longitudinal center valve; shaft J as well as for the two rock-shafts C C They also serve to reinforce were together. the members of the center sill when the same saddle-pieces P are provided with ears or lat -is composed of more than one I-beam. The p eral extensions P P" on each'side thereof to j providea means of attachment for the tension or connecting .membersl which join the fixed section of the chute to the saddle-piece. These members 1 are-preferably, though not necessarily; formed from a blank of sheet.-

r'netal and perforated about as shown in Fig.

7 and then forged or bent into the shape .shown in "Fig. 8. In this, condition they are straddled over the ears P and. secured 'theretoby rivets or bolts, while their parallel extensions 2 at the other endembrace two joined contiguous flanges F- ,of the' fixed 'chute-section-F; being secured to the opposite sides thereof. -The apertures 3 of the g,

folded sides 4 of the said members are adapted to support the longitudinal hinge-pins E, above referred to, which carry the hinge-eyes 5, the latter being formed with long bases 6,

5 which are secured to and serve as reinforcingcleats for the ends of the several plates which comprise the pivoted chute-section E. The fixed or other section F of. the dischargechute is built up of a number of flanged plates united by their flanges F or otherwise to form a unitary structure, it being under stood, of course, that the chute-sections E and F are both symmetrically located on opposite sides of the center sill, as shown in Fig.

I 5 1, and extend'substantially the full length, of the vehicle. The several plates which form the said sectionsare preferably formed with the longitudinal flanges or lips 7, as shown in the drawings. The outer or free end of each fixed chute-sectionis supported and braced from the center sill by means of transverse struts 8, which are formed of ordinary anglebars suitably bent at their opposite ends for attachment respectively to the contiguous zs'flanges F of two adjacent plates of chutesection F and to the web or other convenient part of the center sill. connected is reinforced and stayed inposition by means of a bracing member 9, which consists of an angle-bar or angle-iron bent into V shape, as shown, with the apex of the V secured to the center portion of the strut. -One leg 9' thereof extends to the joint between connecting piece 1 and the saddle piece P 3 5 and is preferably secured 'to the same by the same rivets which form the said joint, and the said leg 9 serves as a hanger-stay for the strut 8, restraining it from lateral deviation. The other and shorter leg 9 is connected to 40 the joint between piece 1 and the fixed chutesections F and serves as a brace reinforcing the said joint and cooperating with the other leg to resolve the pressure on the joint into longitudinal compressive strain in the strut. Fillers (not shown) may beplaced between the members of the center sill, if desired, to brace them against the opposite inward pressures to which they may be subjected by the struts. The joint between the apex of the bracing member is most conveniently formed by riveting together the respe'ctiveparallel flanges thereof, afiller 10 being interposed between the two vertical flanges to compensate for the thicknesses of the flangesF and the extensions2 of connecting member 1, with which the strut is connected, as clearly indicated in .Fig. 5'. Y

It will be understood that any desired number of supporting frames and saddle pieces as above described may be located along the length of the center sill and of course that the flanged joints of the chutesection F are disposed inthc same vertical planes,'respectively, as the saddle-pieces, so 5 that the several members of the frame may The strut as thus inclined chutes located respectively on oppobe properly hung from them in the manner above indicated; but the proportions of the several parts is a matter which is entirely within the realm of the builder and may be modified-and adapted in various ways to suit requirements. Moreover, the specific manner of forming the several frame members and of joining the same together niay also be modified and substituted by other wellknown expedients. 7 5
